Repetitive quantum non-demolition measurement and soft decoding of a silicon spin qubit
Xiao Xue, Benjamin D'Anjou, Thomas F. Watson +8
Quantum error correction is of crucial importance for fault-tolerant quantum computers. As an essential step towards the implementation of quantum error-correcting codes, quantum n…
Spatial Noise Correlations in a Si/SiGe Two-Qubit Device from Bell State Coherences
Jelmer M. Boter, Xiao Xue, Tobias S. Krähenmann +10
We study spatial noise correlations in a Si/SiGe two-qubit device with integrated micromagnets. Our method relies on the concept of decoherence-free subspaces, whereby we measure t…
Benchmarking Gate Fidelities in a Si/SiGe Two-Qubit Device
X. Xue, T. F. Watson, J. Helsen +7
We report the first complete characterization of single-qubit and two-qubit gate fidelities in silicon-based spin qubits, including cross-talk and error correlations between the tw…
A new class of efficient randomized benchmarking protocols
Jonas Helsen, Xiao Xue, Lieven M. K. Vandersypen +1
Randomized benchmarking is a technique for estimating the average fidelity of a set of quantum gates. For general gatesets, however, it is difficult to draw robust conclusions from…
